Interconnect Capacitance (intcap)
Intcap is a model that is used for calculation of the interconnect capacitance, which takes into account the local layer composition and the tracks spacing width.It is described in the Phillips MOST Modelbook (Dec.96) as INTCAP model.
(c) Phillips Electronics N.V. 1993,1996
The model is extended by the device parameters lxbelps, lxbelin and lxbelins, according to the specification by H.Okel (I&A Hamburg).
This device is supported within altergroups.
This device is dynamically loaded from the shared object /<install_dir>/tools.lnx86/cmi/lib/5.0/libphilips_sh.so.
